Constructing a 3D Cell


Purpose: To construct a large labeled 3 dimensional model of an animal or a plant cell, with its various organelles and other structures clearly shown.
This task should help you to understand the size comparisons between organelles in a 3D cell. It will give you a chance to show your creative side and your knowledge of cell structure.

Materials: Some ingenuity is needed here. Carefully think the task out before you begin to ensure you have all required materials. Some possible materials are: plastic ice cream container (cell wall) lined with plastic (cell membrane) , table tennis ball with holes in it (nucleus), gelatin – you will probably need to increase the concentration so it will set solid (cytoplasm), plasticine, pipe cleaners, wire, foil, clothes pegs, poppet beads etc.
Procedure: Use your text book, handouts and other references to work out the relative size of the organelles, number of organelles and their relationships to one another. It may be necessary to complete over a few days if using gelatin so that a 3D model is produced. (ie. Layers will be needed)
MAKE SURE YOUR MODEL IS LARGE WITH ORGANELLES AND OTHER STRUCTURES LABELED AND TO SCALE.
